3. Setup Instructions

3.1 Installing the Soldering Tip

1. Ensure the soldering iron is powered off and cool.
2. Gently twist and pull to disassemble the current tip (if any).
3. Align the new soldering tip with the iron's connector.
4. Push and twist to securely install the tip.

3.2 Connecting Power

The SJ1 supports Type-C/DC input with a working voltage range of 5-20V and a maximum input power of 100W. Use the provided A-C or C-C charging cable to connect the soldering iron to a compatible power source (e.g., a standard 65W fast charging head or power bank).

3.3 Static Elimination Expander Installation

To eliminate static electricity and ensure safe operation, especially when working with sensitive components, install the static elimination expander:

1. Plug the extender into the Type-C port of the soldering iron.
2. Connect the grounding wire from the extender to a suitable ground point.
3. Select the appropriate power supply interface (Type-C or DC) on the extender.

4. Operating Instructions

4.1 Power On and Initial Use

Once connected to power, the soldering iron will display its status on the 0.96" color screen. It features a 100W high-power input, allowing for rapid tin melting in approximately 2 seconds.

4.2 Intelligent/Manual Dual Mode

The SJ1 offers two operating modes:

• Intelligent Mode: Automatically identifies the size of solder dots and adjusts temperature accordingly. This mode provides intelligent temperature control without the need for manual adjustment.
• Manual Mode: Allows for 3-speed quick temperature settings or precise manual temperature adjustment as needed.

4.3 Automatic Recognition of Tin Point Size

In intelligent mode, the soldering iron uses a millisecond-level feedback system to automatically identify the size of the solder dot and adjust the temperature for optimal soldering. This makes it easy to handle both small and large tin points.

4.4 Quick Temperature Settings

In manual mode, you can quickly switch between three preset temperature levels:

• Quick Temperature 1: 300°C
• Quick Temperature 2: 360°C
• Quick Temperature 3: 450°C

These settings can be freely adjusted between 60-450°C to suit your specific application needs.

4.5 User-Friendly Settings

The SJ1 features a humanized functional design with various adjustable settings to improve work efficiency:

• Power On Heating: ON/OFF
• Automatic Standby: Adjustable (e.g., 20s)
• Screen Rotation: 180°
• Language Selection: English
• Under Voltage Protection: Adjustable (e.g., 20V)
• Screen Brightness: Adjustable (e.g., 5)
• Standby Temperature: Adjustable (e.g., 200°C)
• Temperature Increase: Adjustable (e.g., 10°C)
• Auto Sleep: Adjustable (e.g., 300s)
• Temperature Correction: Adjustable (e.g., 0°C)

5. Maintenance

5.1 Smart Stay (Intelligent Hibernation)

The SJ1 features a built-in high-precision gyroscope accelerator for real-time sensing of its working status. Users can set automatic standby and sleep modes to prevent dry burning of the soldering iron tip. This intelligent hibernation feature can extend the lifespan of the soldering iron tip by up to 9 times, making it safer and more cost-effective.

5.2 Tip Cleaning and Care

• Always clean the soldering tip before and after use to remove excess solder and flux residue.
• Use the provided cooling sponge (dampened with water) or a brass wire cleaner to wipe the tip.
• Avoid excessive pressure when cleaning, as this can damage the tip.
• Ensure the tip is properly tinned before storage to prevent oxidation.

6. Troubleshooting

No specific troubleshooting steps are provided in the product information. If you encounter issues, please consider the following general advice:

• No Power/Display: Ensure the USB-C cable is securely connected to both the soldering iron and a compatible power source. Verify the power source is functioning correctly.
• Tip Not Heating: Check if the soldering tip is correctly installed and fully seated. Ensure the power input is sufficient (5-20V, up to 100W).
• Inconsistent Temperature: If in manual mode, verify the temperature setting. If in intelligent mode, ensure the tip is clean and making good contact with the solder point.
• Error Messages: If an error message appears on the screen, try restarting the device by unplugging and re-plugging the power cable. If the issue persists, contact customer support.

7. Specifications

7.1 Tip Compatibility

The SJ1 intelligent soldering iron is widely compatible with most soldering iron tips of the same model on the market, including Aihuo brand 210/245 series soldering iron tips and other brands of 210/245 series soldering iron tips. It is also compatible with C245 and C470 series soldering iron tips, eliminating the need to purchase a separate C470 soldering iron host.
